According to Charles, “Summit has given me a reason for being.” The responsibility of caring for her gets him up and out of the house. When Charles suffers from a flashback, Summit senses it and nuzzles him to redirect his attention to her, and when he has a nightmare, she licks his face to wake him up. Charles uses a cane to walk, so Summit gets the phone for him, picks up dropped items, carries notes to Toni and performs many other tasks to make his life easier. Charles must take a number of prescription medications but says that “Summit is the best medicine of all.”
